Application filed April 13, 1900. Serial No. 12,723. iNo model.)

To a/ZZ whom t Wha/y concern.-

Be it known that I, NELSON P. BRADIsH, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Sofa- Beds; and I do hereby declare that the following is a full, clear, and eXact description of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention is a sofa-bed which for sanitary purposes may be renovated, with a saving in time and labor; second, to secure the movable back to the sofa in an upright position, and enable the parts of said back to be unfolded, in a movement toward a horizontal position; third, to utilize the bolt-operating lever to support the back in a horizontal position, and, fourth, to check the movement of the folding back when the position of the back is changed.

The invention consists in the novel construction and combination of parts, such as will be first fully described, and specifically pointed out in the claims.

In the drawings,`Figure l is a front view of the i'm proved sofa-bed with the folding back in an upright position. Fig. 2 is a rear view in perspective of the improved sofa-bed, showing the folding bed in an upright position and the back-securing devices, also showing in dotted lines the folding back in a horizontal position. Fig. 3 is a transverse sectional `view of the folding hed, showing the device for checking the rearward movement of the folding back. Fig. 4 is a broken detail view of one end of the sofa-bed, showing the position of the back folding rails or bars in describing a rearward movement. Fig. 5 is a broken detail view in perspective of one end of the main horizontal frame of the sofa-bed, showing the front and rear longitudinal bars and the transverse spring-supporting bars. Fig. 6 is a broken detail view in perspective of one of the lower pivoted folding bars forining part of the back of the sofa-bed, showing broken portions of the longitudinal bars connected therewith and the transverse springsupporting bars.

Similar letters of reference indicate corresponding parts in all the figures.

Referring to the drawings, A represents the rectangular-shaped main sofa-bed frame, and B the movable hinged back thereto.

The frame A, which supports the seat of the sofa, is constructed as follows: At each end of the sofa-'bed are two upright bed supports or posts ct a', which are arranged a suitable distanoe apart or so as to afford, preferably, a space between the posts more than one-half of the full width of the sofa-bed when the movable back is reclined in position. The front post a. extends in height a short distance above the plane of the seat of the sofa. The rear posts 0, ct', however, eX- ltend in height to a position so far above the plane of the seatas to be engaged by the locking-bars upon the movable back, hereinafter described. With the respective upper ends of the posts a. is connected one end of the arm a2 of the sofa, which extends in an outwardly-curved line, as at d3, a short distance, and thence extends forward in a downwardlycurved line, and the other" end connected with the upper end of the post a. With the outer side portions of the posts a a, a short distance above the lower end of said posts, are connected the respective ends of a longitudinally-extended bar or rail a4. With the inner sides of the respective posts a a' at each end of the sofa-bed is connected a transverse bar a5, which is arranged in position a short distance below the horizontal plane of the bar a4 on the posts a a'. A short distance above and parallel with the bars a5 and connected with the inner side of the posts a a' are the bars or rails a6. With the outer sides of the bars a5 a6 at each end of the sofa-bed are the vertical bars a7, which are short in length and arranged at short distances apart, said bars serving to retain the pillow in place when the sofa-bed is used. The rear longitudinal bar a8 of the sofa-bed is connected at the ends with the bars a5 a5 at a point a short distance from the posts a a toward the posts a a., so as to afford a clear space for the springs on the movable hinged back, as seen in Fig. 3.

a9 represents the spring-supporting bars, which extend in a transverse direction to the sofa-bed, a portion of the outer ends of which IOO bars are bent at right angles and extended upwardlya short distance and connected with the inner side of the bars a4, the rear end portion of the bars extending in a horizontal direction and connected with the inner side portion of the longitudinal bar as. Upon the upper horizontal surface of the bars a9 are the spiral springs n10, which are held in position with wire or rope in the usual well-known manner. The springs am are preferably ineludedA within a spring bed-bottom of the proper dimensions and placed upon the bars n.9. Upon 'the spring ctlois a cushion or mattress C of the same width as the spring bedbottom or the space between the bars a4 a2. With the under side of one of the bars @9,10- cated at a point equidistant from the ends of the sofa-bed, is connected a plate or bar cl2, (see Fig. 3,) the rear end portion of which bar extends beyond the vertical plane of the bar a2, so as to afford a bearing for the check of the movable back B, as hereinafter described.

The movable back B consists of separate upper and lower folding bars b b at each end of the sofa-bed, which are preferably shorter in length than the bars a5 a6. One end of these bars b is connected by the pivot hX with the inner side portion of the respective bars a6 a6 at points upon a vertical line equidistant from the post a and the rear vertical bar a7 of the sofa-bed. With the outer ends and side portions of the upper bars b b are connected by the pivot b9 the folding upright dat bars or posts 52122, the upper ends of which posts extend but a short distance above the pivotal point of the upper bars b and are connected by a horizontal bar or rail h3, which serves to, keep the clothing upon the movable back when in a horizontal position. The lower bars h h at their inner ends are pivotally connected bythe pivots bX with the inner sides of the bars a5 a5 at points vertically in line with the pivotal points of connection of the inner ends of the bars b b with the bars ci,6 a6. The outer ends of said bars bb are pivotally connected by the pivots bo with the inner sides of the posts h2 b2 at the same distance from the pivotal points of their inner ends as is the distance between the pivotal points of the outer and inner ends of the bars b b. Said bars b b extend a short distance beyond the outer edge of the posts b2 b2, and the outer ends are bent in a curved line inwardly and the said curved ends connected by a longitudinal bar b4, integral with said .arate spring-supporting bars bm.

said'barfs h' b as far as the lower ends of the posts a o', below the pivotal innerends of said bars, so as to form supporting-legs for the back B when in a horizontal position. With the outer side portion of the longitudinal bar b4, at the point b5, which is intermediate to the length of'said bar, is pivot-ally connected the lever h6, the longest portion of Whichlever extends to the floor and forms a leg or support to the backrB when the said back is in a horizontal position. Extending around the bar b4 are separate slidable loops he hg, which are arranged near each end of bar b4. With the portion of the loops 58198 on the outer side of bar b4 are connected pivotally the outer endsof the respective bars 57 b9, the inner ends of which bars are pivotally connected with the outer side portion of the lever h6 at equal distances from the pivotal point b5 of said lever. The outer ends of the bars 197 b9 are thrust outwardly in position by the lever b and engage with the inner side of the curved portion a3 of the arm a2 of the sofabed when the back B is in a vertical position.

At each end of the movable back B are sep- Each bar 514 is bent at right angles at the outer ends and said bent portions secured in a transverse direction to the back B to the respective bars b4 and 612. Upon the inner sides of bars Z914 are horizontal slats Z916, upon which are springs Z915 on respective opposite ends of the slats bm. Upon the springs hk': is placed the cushion or back to the sofa C', the width of which is in excess of the width of the back B of the sofabed between the bars h4 Z912. The upper sides and inner edges of the cushions C O' are connected in any suitable manner at c, (see Fig. 3,) so that as the back is moved rearwardly -the cushions close together and form a conwhen the'back is in an upright position support said cushion in position. The checking device for the rearward movement of the back B consists of a bar D, which is the same in construction as the bar Z914, but slightly longer, one end being curved outwardly at d and connected with the inner side of the horizontal bar h4 of frame B, and the outer curved portion CZ', extended beyond the outside of the bar Z912, caused to rest upon the upper surface of the end of the bearing plate or bar 01,12, the weight of the back B also being sustained at this point, the bar also being riveted to the horizontal slats Z916. Connected with the under side of the plate cl2 beneath the end of bar D is a leg dla, which extends to the floor.

' The lower ends of the parts ct a/ and the leg als are provided with casters ax.

In the ordinary use of the sofa-bed as a sofa the sliding bars 57 b2 retain the movable back in a vertical position, the ends of the said bars being concealed by the cushion C. When required to be used as a bed, the hooks c' c on cushion C are detached from bar b3 IIO ` rearwardly and the bearing angular end d of bar D resists automatically the sudden fall of the back, so that the movement is readily controlled. In the described rearward movement the folding bars b b spread apart and the t posts b2 b2V of the back, which retain an invariable vertical position, are placed upon the floor, the bars b b and a5 a of frame A being in the same horizontal plane and the cushions C placed upon the springs 615 in the back B, thus forming an even surface upon which the usual coverlet may be placed, as seen in dotted lines in Fig. 2.

The frame of the back and seat of the bed are preferably constructed of metal, from which the cushions are quickly removed for renovation, thus aording the sanitary requirements of this form of bed. In raising the back to a vertical position, as seen in Figs. 1 and 2, the posts b2 fold between the folding bars b b', so that the bars are in a parallel position, as seen in dotted lines in Fig. 4, the posts spacing the bars b b', so that the inner ends of the bars pass each other Without friction. Thelongitudinal bars may be dispensed with in the back B, if preferred, and the bars Z114 increased in number, upon which the spring bed-bottom may rest, and other modifications may be made Within the scope of the invention.

Having fully described my invention, what I now claim as new, and desire to secure by Letters Patent, is-

l. In a sofa-bed, a main horizontal frame and a rearwardly-movable hinged back, and a bearing bar or plate connected with said frame, and a supporting-bar for said back having a lower outwardly-curved end bearing upon said bar.

2. In a sofa-bed a main horizontal frame,

and a rearwardly-movable hinged back to said sofa-bed, a transverse bearing-plate connected with the under side of said frame and having its rear end extending beyond the plane of said back, and a supporting-bar connected with said back, having its lower end curved outwardly and resting upon said bearing-plate.

3. In a sofa-bed a main horizontal frame and a rearwardlymovable hinged back to said sofa-bed, a transverse bearing-plate connected with the under side of said frame and having its rear end extending beyond the plane of said back a leg connected with the under side of said rear end of said bearingplate and a supporting-bar connected. with said back having itslower end curved outwardly and resting upon said bearing-plate.

4. In a sofa-bed, the combination with the main horizontal frame to said bed, of cornerposts at the rear end of said frame extending above said frame, and a rearwardly-movable frame for the back of said sofa-bed comprising separate folding longitudinal bars pivotally connected at suitable points on the main frame,one above another, in a vertical plane, and posts pivotally connected with the outer ends of said bars and with the outer side of the upper bar and the inner side of the lower bar, and longitudinal upper and lower bars connecting said posts with each other, a lever pivotally connected with the lower bar at a point intermediate the posts, and adapted to support the back when in a horizontal position, and guides, upon said lower bar, and sliding bars controlled by said guides extending in opposite directions, and adapted to engage with the posts upon the inner frame, when the back is in a vertical position, and having the inner ends of said bars pivotally connected with the said levers upon opposite sides of the pivotal point of connection of said lever with said bar.
